3981 PTFE-coated Washers, 6x9.5x0.5mm (10) (use with ball bearings)

The 3981 PTFE-Coated Washers are precision-engineered components designed to reduce friction and provide smooth operation when used with ball bearings in RC vehicles, drones, or other precision machinery. Each washer is coated with PTFE (Teflon), offering superior wear resistance, low friction, and long-lasting performance, even under high-speed and high-load conditions.

This 10-pack of washers ensures proper spacing, alignment, and protection of bearings, helping extend the life of both the bearings and shafts. PTFE coating also reduces heat buildup, improves efficiency, and prevents metal-on-metal contact in high-stress areas.
